Description
Scientific Anglers Mastery Trout GP is a finesse-oriented general purpose taper built for trout anglers who prioritise delicate presentations over heavy rigs. Utilising the tapered belly from the Infinity with a slightly longer front and rear taper and a quarter-size-heavy weight scheme, this line delivers smooth accurate casts across a wide range of techniques. It excels with dries, nymphs, and moderate streamers, making it the ideal choice for anglers who don't consistently fish large streamers or bulky indicator setups.
Technologies
- AST – Advanced Shooting Technology slickness additive that reduces friction, improves shootability, and keeps lines performing longer.
- Welded Loops – Durable welded loops on both the front and back of the line for easy, reliable loop-to-loop connections to backing and leaders.
- SA-ID – Printed line identification for quick, easy recognition on the water.
- Braided Multifilament Core – Supple cold-water core that improves flotation, reduces memory, and provides smooth, stable casting.

Mastery Line Features
SA Mastery Series lines have been among our most-popular and best-performing lines. Mastery Series lines still deliver just as well as, if not better than they ever have before.
With the AST slickness additive, Dry-Tip technology, colour change at the rear of the head, and SA Line Identification system, Mastery lines are still the best smooth lines at their price point on the market.
